SPINNING AND TWIS'IING MACHINE.

Application filed January 13, 1910.

To all whom it may concern:

Be it known that I, FREDERICK S. CULVER, a citizen of the United States,residing at Taunton, in the county of Bristol and State ofMassachusetts, have invented a new and useful Improvement in Spinningand Twisting Machines, of which the following is a specification.

This invention relates to improvements in appliances for spinning andtwisting machines.

laiore particularly, it pertains to adjustable holders or clamps forguide wires and separators located upon the top rail of a spinning ortwisting machine.

The object of the invention is to construct a simple and effectiveholder which may be clamped around the top rail of the machine in anydesired position and is adapted for use to hold either guide wires orseparators.

Further, it is an object to construct these holders so that they may beproduced in large quantities from sheet metal, and at comparativelysmall cost.

Viith these objects in view, the invention will now be hereinafter fullydescribed, reference being had to the accompanying drawings, in which,

Figure 1 is a transverse sectional View of a part of a spinning machine,showing the bobbin rail and the top rail, with the usual equipment. F i2 is a front view of the section of the machine shown in 1. Fig. 3 is aperspective view of the holder forming the subject matter of thisinvention, showing it clamped to the top rail. Fig. -ft is a perspectiveview of one member of the holder. Fig. is a perspective view of thecompanion member, and Fig. 6 is a view of the holder having a separatorsecured thereto.

Referring more particularly to said drawings, 1 is the spinning orbobbin rail upon which are carried the spindles which support bobbins 2;3 is the top rail, 4 are guide wires and 5 are separators. Clampedaround the top rail 3 and holding said guide wires at and if desired,the separators 5, are the holders 6. Said holders 6 each consist of twomembers, a top or supporting member 7 and a companion or clamp member 8.

The top or supporting member 7 has secured thereto the guide wirestructure or the separator-plate, and consists of a sheet metal platehaving a top horizontal member which extends across the top of the toprail l Specification of Letters Patent.

3, and projects over the front edge of the latter to form a trough likeshelf 9 and a bar or rail engaging element 9. Said shelf 9 is formed byturning up the opposite sides of the projecting portion and is providedwith a longitudinal slot 10. Said slot 10 forms an adjustable bolt holeto receive the bolt or screw 11 by means of which the hinge plate 12 ofthe guide wire at is fastened to the holder, or, as shown in Fig. 6, theclamping plate 13 of the separator may be thus secured to the shelf 9 inthe same manner. The bar or rail engaging element 9' is formed bycontinuing the member 7 downwardly and then bending it inwardly as at14c and 15 to embrace the rear side and the bottom of the top rail 3.The forward edge of the portion 15 is provided with a centrallyapertured downturned ear 16, whose function will hereinafter appear.

The companion member or plate 8 consists of a sheet metal plate having acut-away portion or indentation 17 to permit the plate 8 to bear againstthe front face of rail 3 and to embrace by cars 18 the sides or edges ofthe shelf 9, where the latter projects over the edge of said rail 3. Thesaid upwardly projecting ears 18 not only embrace the edges of saidshelf 9, but lie behind and interlock with the out-turned projections orfingers 19 which are formed by moving the rear ends of the upturnedflanges forming the sides of the shelf 9 from said shelf and bendingthem laterally at right angles to said shelf. The upper projecting endsof the ears 18 are also overturned, as at 20 to overlie the fingers 19,thus completely interlocking the two members 7 and 8 of the holder atthe top of the rail 3. The bottom of plate 8 is provided with adownwardly projecting apertured car 21 which is adapted to register withthe ear 16 when said members 7 and 8 are interlocked around the rail 3,and receive a set screw or bolt 22 to rigidly attach the holder to thetop rail.

It is evident from the foregoing description that the holding device iswell'adapted to be clamped to any top rail or guide rail of spinningmachines and to hold either or both the guide wires, and the separators.Also, that its construction is simple and well adapted to be made inlarge quantities at comparatively small cost, owing both to itssimplicity of manufacture and the small amount of sheet materialrequired in a single holder,

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A guide wire holder for spinning machinescomprising, in combination, a supporting member composed of a shelf andportions adapted to embrace the top, bottom and rear faces of a toprail, and a clamp member arranged against the front face of said rail,said clamp member being interlocked with said shelf at its upper end andbolted to said supporting member at its lower end below said rail.

2. A guide wire holder for spinning machines comprising, in combination,a supporting member and a clamp member, said supporting membercomprising a shelf mem ber and portions adapted to surround the top,bottom and rear sides of a top rail, and having locking projectionsformed thereon, and said clamp member consisting of a plate formed tointerlock with said locking pro jections and to be bolted to saidsupporting member below the top rail.

3. A guide wire holder for spinning machines comprising, in combination,a supporting member and a clamp member, said supporting membercomprising portions adapted to embrace the top, bottom and rear faces ofthe top rail, a horizontally forwardly projecting shelf member having alongitudinal bolt slot and locking members formed thereon, and saidclamp member comprising a plate adapted to interlock with said lockingmembers at its upper end to be bolted to said supporting member belowsaid top rail.

4. A guide wire holder for spinning machines comprising, in combination,a supporting member and a clamp member, said supporting member beingadapted to embrace the top, bottom and rear faces of the top rail andhaving a depending bolt ear and a forwardly projecting shelf, and earsprojected laterally from said shelf adjacent the upper edge of the toprail, and said clamp member comprising a plate adapted to lie againstthe front face of the top rail, a depending bolt ear adapted to registerwith the bolt ear on said supporting member, and upwardly projectingmembers adapted to embrace the sides of said shelf and to lie betweensaid laterally projected ears and the top rail and forwardly projectingfingers formed on the upper ends of said shelf embracing members andadapted to overlie said laterally projected ears, whereby the upper endof said clamp member may interlock with said supporting member and thelower end of said clamp member may be bolted to said supporting member.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
